To all whom it may concern:

Be it known that I, HARRY D. THOMAS, citizen of the United States, residing at Cincinnati, in -the county of Hamilton and State of Ohio, have invented certain new and useful Improvements, in Dishashing Machines, of which the following is a specification. 7 v

yinvention relates to improvements in dish-washing machines.

One of its objects is to provide simple and .eificient mechanism which may be 0 erated by hand or by power for washing or c eaning dishes. I r

. Another object is to provide an improved circulation of the cleansing liquid and means for maintaining suchcirculation.

I Another object is to provide a dish-holding basket and means for supporting and rotating the sanie.

It further consists incertain details of formjcombination and arrangement, all of which will be more fully set forth in the description of the accompanying drawings, in which;

Figure 1 is a top plan view of my improved mechanism.' Fig. 2 is a central vertical sec:

tion on'line o''v of Fig. 1.- Fig. 3 is a sec tional diagram on line. 2z of Fi .2 illustrating the path followed by the circulating cleansing medium. Fig. 4 is a view similar to Fig. 3 illustratingthe arrangement of two baskets in connectionwith one circulating.

member. Fi 5 is a detail of one of the circulating mem ers or blades. spective View of one of the stationary de ectors. Fig. 7 is a erspectiv'e view of one of the removable has ets. 8 is a detail of a basket with bail and swive support.

In the accompanying drawings, 'A represents thesu porting frame, B'represents' a tank in Whic the dishes are cleaned, and B a tank containing clean boiling, water in which the dishes may be rinsed. T

The tankBfs. preferably com osed of a cast metal bottom 6, sheet met side walls b and acast metal topplate b havin an openin I 6 over tankB Thetank f is similary formedexce'pt that it is entirely open at thetop; the top'plate b is to be extended to encircle the upper edges of tank B and be provided with raised ribs or rims around the tank openings anda raised outer rim b*,., and a 'drain b to catch andconduct Fig. 6 is a er- 3 away' any water which may be spilled or splashed from the tanks.

' C representsa rotating frame orskeleton basket composed of the hub c which is journaled and supported upon the bottom of tank B at c and a series of arms 0 projecting radiall'y'from said hub and carrying upwardly projectin arms 0 which are united at their upper en s by a circular band 0". secured by lugs to the top late 5 v A vertical shaft '0 carried by hu l) 0 passes downward through a journal box 0 and stufling Arim c is box c and is provided at its lower end with a gear 0. by means of which A detachable perforated basket D which may be formed from perforate sheet metal or power is transmitted to rotate the frame C.

woven Wire'is adapted to be seated over the radial arms 0 and u on the lower horizontal ends of arms ('2 an 'laterallysupported by the vertical arms 0 The basket D is provided with lugs on feet at which engage the lower horizontal ends of arms 0 so that the rotary motion of frame C is imparted -to liquid contents of tank B, so as to bring the;

liquid into intimate contact with all parts of the dishes in basket D. In order to enable liquid throughthe basket, I provide the blades with forwardly turned upper and lower edges e e, and also rovide a stationary deflector late F attac ed to the side of the tank, .pre erably on the opposite side of the basket from shaft E and a stationary de ilector plate G attached to the bottom of the tank beneath the basket to deflect the liquid upwardly into the bottom of the basket.

H represents the main driving shaft which may be driven by belt and pulley, or other driving ear, for lar e machines, or maybe provide with a cran and operated by hand in smallgnachines. Shaft H is provided with a gear h meshing-with the gear 0 and a the blades to most effectively circulate the gear 71/ which engages and drives a gear if our the lower-end of shaft E. The several gears are preferably so pro ortioned that the shaft E rotates more rapid y than shaft 0", in order to produce a vigorous circulation, and to present all parts of the basket to the full force of the current. i

In operation the dishes are packed in the basket D, which is then lifted and seated in the frame C, the tank B being nearly'filled with a warm solution preferably soapy or alkaline. The basket andsh aft E are then r0- tated, which causes the liquid to circulate inthedirection indicated by the arrows in Fig. 3 passing from the: blades through the basket and around to the deflector F, which returns the current into the basket so that the two currents meet in'the basket and mutually deflecteach other. The lower portion of the blades-also direct a strong current into the defiectorG which deflects it upward into the lower portion of the basket. Thus all parts of each dish of whatever shape are subjected to the action of the various currents set up in the liquid and thoroughly cleansed.

After the dishes have been cleaned in tank the basket is lifted from tank B and set into tank 13', where the dishes are rinsed by I which areprefer'a being immersed in .clean hot water and the basket then removed to drain.

Tanks B, B are rovided with drains'g, g,

idly connected by valvecontrolled pipes g 9 with the pipe giwhich leads from drain b Valve-controlled pipes g g",'serve to supply fresh waterto tanks B, B. In practice, hot water is supplied in small quantity through pipe 9 continuously vwhile the machine is in operation, and ale 7 lowed 'to overflow the rim. of tank B -to keep be locatedat either end of tank B a constant sup 1y of clean water in tank B.- Water is supp ied from time to time as required through ipe g As shown in ig. 4 twgqbasket's D, D are adapted to be employed in one tank B in connection with a single shaft E" carrying circulating blades e, e In this form, a rinsing tank such as shown at B Fig. 2, may

The cirthe same as described and indicated in hevme'chanism herein illustrated and described is capable of considerable modification without departing from the principle of my invention.

Having described my invention, what I claim is:
